My research is in the area of artificial intelligence, and includes contributions in the areas of artificial intelligence and education, computational linguistics, spoken language, and user modeling. My work has included both fundamental research and applied research resulting in technology transfer and patents. My most recent research has been in the area of Speech and Natural Language Technology for Educational Applications. Currently funded projects include:

  • (ArgRewrite) Development of Human Language Technologies to Improve Disciplinary Writing and Learning through Self-Regulated Revising
  • (CourseMIRROR) Enhancing Undergraduate STEM Education by Integrating Mobile Learning Technologies with Natural Language Processing
  • (Discussion Tracker) Development of Human Language Technologies to Improve the Teaching of Collaborative Argumentation in High School English Classrooms
  • (eRevise) Response-to-Text Tasks to Assess Students' Use of Evidence and Organization in Writing: Using Natural Language Processing for Scoring Writing and Providing Feedback At-Scale
  • Studying Collaborative Dialogue with a Teachable Robot in a Mathematics Domain
  • Using AI to Increase Fairness by Improving Access to Justice

Brief Biography

I am Professor of Computer Science, a Senior Scientist with the Learning Research and Development Center (LRDC), and Faculty of the Intelligent Systems Program (ISP), all at the University of Pittsburgh. I moved here from the Garden State (aka New Jersey), where from 1985-2001 I was a member of the Artificial Intelligence Principles Research Department, AT&T Labs - Research (formerly Bell Laboratories); From 1990-1992, I was also an Assistant Professor of Computer Science at Columbia University. I received my Ph.D. and M.S. in Computer Science from the University of Rochester, and my A.B. in Mathematics and Computer Science from the College of William and Mary in Virginia. Here are my informal and more formal versions of my academic geneology.
